I came across your code today, and I absolutely love it. I own two Schlage BE496 Deadbolts, and one Schlage FE599 lever, and adding and removing codes from them can be quite the hassle, so your work has made my life much easier. Thank you!
On another note, the BE496 deadbolts are made with a 90db alarm that can be configured to sound when someone enters/leaves, when it senses tampering, or when it senses a forced entry. I also own a Fortrezz Siren Strobe, and I am looking for a way to tie these three alarms together to work in unison. Some other folks have done some work with these Schlage locks, and having the alarm triggers send off actions to other devices, but I was hoping that there may be a possibliity for you to integrate this functionality into your custom device and app as well. Here are a couple examples for you:
